Again, I'm playing devils advocate for a pro-walled-garden opinion me myself don't believe in, so don't take my opinion too seriously.
Pure cynicism on my part by default, so it's all good, mate.
App Store, Gatekeeper, etc are now working against what they were supposed to solve and encouraging worse developer behavior.
Really the best solution would be tackling the reasons why Zoom are doing this in the first place. Like how they provided a gentler version of Sandboxing to work around pro creative apps being basically unusable in the first versions.
The more you lock it down the more bad behavior you'll encourage from less ethical developers.
Are you talking about something else or am I misunderstanding here?
